"While the first movement of "Aérea" shows the most "opulent" aspect of Ruth Barberan and Alfredo Costa Monteiro, who blow into trumpet and accordion with all their force like if they had to deliver themselves from years of frustrating muteness, the remaining parts are more typical of these artists' "post-timbral" harshness and irony. Ruth's initial sequences of more polite notes soon become a skating figure rotating all over your teeth, her cynical games of air and tongue assuming the role of a pulmonary power plant emitting shrieks and metallic fury. Alfredo approaches his accordion with a bright sense of investigation, generating layer upon layer of disembodied harmonics that are washed away by the tides of a dirty insistency, his dissonant potential at times exquisitely refined and detailed but more often tending to a barely controlled pressure. The couple is venomous - but this music is delicious."-Massimo Ricci (Touching Extremes)
